DETAILED DESCRIPTION OF THE EMBODIMENTS

The design scheme of the present invention to achieve the aboveobjectives is:

Referring to FIGS. 1 to 3, a reciprocating hair removal device for floorcleaning comprises a roller brush 1 and a first driving structure 2 fordriving the rotation of the roller brush 1, and a tufting bundle 11 isprovided on the surface of the roller brush 1; further comprising asliding rail 3 disposed parallel to the roller brush 1 and a slidingblock 4 slidably coupled to the sliding rail 3; the surface of theroller brush 1 is formed with a first spiral groove and a second spiralgroove with a reverse direction, and the head ends of the first spiralgroove and the second spiral groove are connected, and the tail ends ofthem are connected to form a reciprocating spiral groove 12; the slidingblock 4 is provided with a hair removal knife 41 with one end extendingto the reciprocating spiral groove 12; the hair removal knife 41reciprocates along the reciprocating spiral groove 12 with respect tothe roller brush 1 when the roller brush 1 rotates. During the processof cleaning the floor, when a strip such as hair or a wire is woundaround the roller brush 1 in the circumferential direction, the rollerbrush 1 is rotated at a high speed at this time. Therefore, the hairremoval knife 41 also slides at a high speed along the reciprocatingspiral groove 12 with respect to the roller brush 1, thereby cutting offthe strip-shaped foreign matter such as hair wound on the roller brush 1from the position of the notch of the reciprocating spiral groove 12. Inaddition, the existing floor cleaning equipment is basically equippedwith a vacuum cleaner, and the cut hair and the like are finally suckedaway by the vacuum cleaner, so that the foreign matter such as the hairwound around the roller brush 1 is directly removed without stopping theroller brush 1 cleaning operation.

The sliding of the hair removal knife 41 and the sliding block 4 can bedriven by the groove wall of the reciprocating spiral groove 12 when theroller brush 1 is rotated, or by other driving structures, because ofthe reciprocating spiral groove 12 pushing the hair removal knife 41 andthe sliding block 4 to slide, there is a higher speed contact frictionbetween the hair removal knife 41 and the groove wall of thereciprocating spiral groove 12. In this embodiment, in particular, inorder to reduce wear and increase the service life, a second drivingstructure for driving the sliding block 4 to reciprocate along thesliding rail 3 is further included, and the second driving structureincludes a reciprocating screw rod 5 that cooperates with the slidingblock 4, and the reciprocating screw rod 5 is parallel to the slide rail3 to drive the sliding block 4 through the reciprocating screw rod 5 todrive the hair removal knife 41 to move. And in order to make themovement of the hair removal knife 41 consistent with the rotation ofthe roller brush 1 and always in the reciprocating spiral groove 12, inthe embodiment, the second driving structure includes a secondarytransmission mechanism 6, and the roller brush 1 drives thereciprocating screw rod 5 to rotate simultaneously by the secondarytransmission mechanism 6. In particular, the secondary transmissionmechanism 6 includes a secondary active synchronous wheel disposed onthe roller brush 1, a secondary driven synchronous wheel disposed on thereciprocating screw rod 5, and the secondary synchronous belt connectingof the secondary active synchronous wheel and the secondary drivensynchronous wheel. Of course, according to the actual situation, thesecondary transmission mechanism 6 can also adopt other types oftransmission mechanisms, such as a gear transmission mechanism, inaddition to the synchronous wheel transmission mechanism, as long as thetransmission ratio is relatively constant during the transmissionprocess, for example, a method of providing a secondary driving gear onthe roller brush 1 and a secondary driven gear meshing with thesecondary driving gear on the reciprocating screw rod 5 may be adopted.

In the present embodiment, preferably, the surface of the roller brush 1is provided with a plurality of spiral protrusions 13 between which thereciprocating spiral grooves 12 are formed. Moreover, preferably, thespiral protrusion 13 is made of soft rubber, because the soft rubber haselasticity, and can avoid the damage caused by the collision with theground during the cleaning operation of the roller brush 1, which isbeneficial to improve the service life. Of course, according to theactual situation, in addition to the soft rubber, the spiral protrusion13 can also be formed by integrally forming with the roller brush 1; andthe reciprocating spiral groove 12 can also be formed directly on thebody of the roller brush 1 by slotting.

In this embodiment, specifically, the hair removal knife 41 is providedwith a hook-shaped blade 411, and one end of the hook-shaped blade 411away from the sliding block 4 is disposed in a hook shape structure, andthe blade edge is disposed on the inner side of the hook shape structurein order to loosen and cut the foreign matter such as hair wound on theroller brush 1; and the hook-shaped blade 411 is provided with twopieces, and the backs of the two hook-shaped blades 411 are connected ina V shape in order to improve the overall rigidity of the hair removalknife 41, and the problem that the hair removal knife 41 is bent or evenbroken due to excessive resistance of the foreign matter such as hair onthe roller brush 1 is avoided. Specifically, when the hair removal knife41 is located in the first spiral groove, one of the hook-shaped blades411 is parallel to the tangent line of the first spiral groove, when thehair removal knife 41 is located in the second spiral groove, the otherof the hook-shaped blades 411 is parallel to the tangent line of thesecond spiral groove; so that the hair removal knife 41 has onehook-shaped blade 411 in the process of going back and forth, cuttingthe hair along the tangential direction of the reciprocating spiralgroove 12.

In the present embodiment, in order to prevent the hair removal knife 41from damaging the tufting bundle 11 during the reciprocating motion, inparticular, the tufting bundle 11 is evenly distributed on the rollerbrush 1 and keeps away from the position of the reciprocating spiralgroove 12.

The above is only a preferred embodiment of the present invention, butthe present invention is not limited to the above embodiments, and aslong as it achieves the technical effects of the present invention byany identical or similar means, it should fall within the protectionscope of the present invention.
